The company has achieved solid growth with revenues of $24.8 million in 2006, compared to $19.8 million in 2005. AirLink had earnings from operations of $3.9 million in 2006 and gross margin of 44%.

“The acquisition of AirLink Communications is consistent with our strategy of renewing and strengthening our emphasis on higher gross margin products and solutions”, said Jason Cohenour, President and Chief Executive Officer of Sierra Wireless. “We believe that combining AirLink’s leading modem and software products business with our rugged MP product line creates a focused, well-positioned leader in the mobile and machine to machine (M2M) segments of our market. Furthermore, we believe that the business from these market segments has solid growth prospects and an attractive gross margin and operating margin profile. We view AirLink as an important strategic addition to our overall business.”

“By joining forces with Sierra Wireless, AirLink gains access to global distribution channels, leading edge wireless technology, large scale manufacturing and supply chain capabilities and working capital to drive future growth. We bring a multi-tiered suite of wireless connectivity devices powered by robust embedded software, a broad set of software tools and utilities for device management and strong working relationships with North American network operators, integrators and application providers”, said Andrew Berman, Chief Executive Officer of AirLink Communications. “We are enthusiastic about becoming the driving force behind Sierra Wireless’s Mobile and M2M business.”
